In this paper, we propose a novel bicubic method for digital image interpolation. Since the conventional bicubic method does not consider image local features, the interpolated images obtained by the conventional bicubic method often have a blurring problem. In this paper, the proposed bicubic method adopts both the local asymmetry features and the local gradient features of an image in the int...
Image scaling is a technique which scale down or scale up the pictures or video frames to fit to the application. This work proposes a new scaling algorithm for the implementation of image scaling. The proposed scaling algorithm is an area pixel scaling algorithm consisting of a Discrete Wavelet Transform (DWT) based interpolation and bicubic interpolation. To achieve higher visual quality, DWT...
Aim: To assess whether retinal vascular caliber measurement from digital fundus photographs using IVAN software (University of Wisconsin, Madison, WI) is affected by bicubic image interpolation using image processing software (Photoshop version 5.5, Adobe Systems Inc., San Jose, CA). Material and methods: 32 good quality optic disc centered retina photos (slides) acquired in healthy volunteers ...
We discuss linear methods for interpolation, including nearest neighbor, bilinear, bicubic, splines, and sinc interpolation. We focus on separable interpolation, so most of what is said applies to one-dimensional interpolation as well as N-dimensional separable interpolation. Source Code The source code (ANSI C), its documentation, and the online demo are accessible at the IPOL web page of this...
